ich habe das Artikelmodul von Evert Smit / Dirk Uptmoor / Peter Beauvain, mit der Thumbnailvorschau. Bei mir werden die Thumbnails nicht erstellt. Das Bild erscheint zwar, aber leider nur in der tatsächlichen Größe. Meine GD Kentnisse sind leider sehr dürftig. Habe schon viele Threads zu dem Thema gelesen, bin aber nicht weitergekommen. Wäre sehr nett wenn mir jemand weiterhelfen könnte.
Hier ein Auszug aus dem Modul wo die Thumbnails erstellt werden:
Meine Konfiguration:/******************* begin thumbnails **********************************/

$db2->query($imagesql);
$db2->next_record();
$image_id= $db2->f("value");
// get image name and path
$imagesql="select * from ".$cfg["tab"]["upl"]." where idupl='$image_id'";
$db2->query($imagesql);
$db2->next_record();

$imageattributes = $fileinformation[3];

$target=$thumblocation;
if ( !(copy($imagelocation,$target)))
{
echo "Could not copy file to destintaion., Command returned Error Message. Please check your log files. ".$imagelocation." ".$target;
die;
}
//create thumbnails 80xrelational height; neu $thumbnail_width x proportionale Höhe
// Determine what filetype and set pointer to source image
$original_image=ImageCreateFromJPEG($target);
if (!$original_image){
echo 'Error getting image from '.$target.'.';
}
$palette_image =$filedir.$webdir.$thumbdir.'vorlage.jpg';
$thumbsize = getImageSize($palette_image);
$maxdim = $thumbsize[0];
$draw_from = $imagelocation;
$dim = GetImageSize($draw_from);
if($dim[0]>$dim[1])
{

$to_x = 0;
$to_y = round($maxdim-$to_h)/2;
}

$to_h = $maxdim;

0, $to_w, $to_h, $dim[0], $dim[1]);
//echo $target;
